<div>
<pre>MacOS's SDK does not include the uchar.h header, and since these macros are
defined by the compiler the macro check doesn't work, breaking my code.
I filed a bug report with Apple about it, bug #51322492 but they don't seem to
care.
Example code to get the bug to appear:
#ifdef __CHAR32_TYPE__
typedef char32_t UTF32;
#else
typedef uint_least32_t UTF32;
#endif /* __CHAR32_TYPE__ */</pre>
</div>
